(PhysOrg.com) -- Researchers working out of the National Institute of Advanced Industrial Science and Technology (AIST) in Tsukuba, Japan have developed a means for printing thin film transistors using InkJet technology. ...
(PhysOrg.com) -- It seems like small displays are all of the rage these days, and they just keep getting more and more advanced. In October of last year Ortus Technology created a 4.8-inch liquid crystal display that showed ...
NIST researchers grow nanowires made of semiconductors -- gallium nitride alloys -- by depositing atoms layer-by-layer on a silicon crystal under high vacuum. NIST has the unusual capability to produce these nanowires without ...
